1.4.2 Upflow Units
Upflow units will typically be supported by vibration isolation pads and/or floorstands which
and may also include leveling screws. An air discharge plenum may be factory provided which
ships loose and must be attached at the top of the unit frame.
Alternately, an air distribution plenum must be field fabricated with supply grilles to distribute
the air. Units are shipped with a drive package to overcome external static pressure. Adjustments
to the blower speed may be required to adjust to actual conditions.

Paperwork
Each Data Aire unit ships with a start-up sheet that should be completed during installation.
Also included in the paperwork is a warranty/information packet that provides important wiring
diagrams, specific component literature, warranty registrations cards and other valuable paperwork,
including a copy of this Installation/Operation and Maintenance manual.
A yellow tag is attached to the outside decorative door to indicate articles that may have
been packaged and shipped loose within the unit cabinet. Typically this would be jackstands,
condensate pumps and other loose components that are not factory mounted.
1.6
Storage
Your Data Aire equipment comes ready for immediate installation. In some instances in may
be necessary to store the equipment for a period of time. If you must store the equipment it should
be done in a dry area, out of the weather, protected from damage by other equipment in storage or
transportation equipment, never stacked, and avoid frequent relocation.
If equipment is stored for longer than 30 days special precautions must be taken to avoid coil
damage. All coils should be charged and sealed with a low pressure (1-25 psig) inert gas, such as
nitrogen. This prevents contaminates from entering the coils; then when the seal is broken at
installation, the rush of escaping gas verifies the coil is still leak free. If coils are not charged and
sealed condensation mixes with air pollutants forming a weak acid and over time can cause pin hole
leaks to develop in the coil tubes.
When equipment is installed after storage caution should be taken to inspect and replace, if
required, rubber hoses and belts. All moving parts, such as blowers and motors, should be hand
tested to ensure that they are free and clear prior to start-up. Finally, verify that all lubrication is
fresh and full.
It is the responsibility of the installing contractor to return the start-up sheet and warranty
registration card to Data Aire for proper activation of the unit warranty. Failure to do so
may cause delays and in some cases void the warranty.
